Christmas dinner at my mums this year. DP has been quite sulky not really joining in. Mum spent ages trying to make dinner perfect. He starts eating and says ‘sorry I’m going to have to spit this out it’s too fatty’, and almost spat it out at the table before I asked him to leave to do it. Then when everyone else was still eating, got up as soon as he was finished to go for a cigarette, leaving my family feeling really awkward. We’ve been together three years, it’s never happened before - AIBU to feel really embarrassed by this?
